The number of pass candidates are 2 + 6 + 18 + 40 = 66 out of total 100.
Hence, Pass percentage = 66%
3+1 = 4
4+3 = 7
7+1 = 8
8+3 = 11
11+1 = 12
12+3 = 15
⇒ Let total examines is x.
⇒ 65% of total examines has passed.
⇒ student failed =100%−65%=35%
Then, 35% of examines have failed.
⇒ Number of failures is 420
∴ 35% of x=420
∴ 35x/100 = 420
x=(420 * 100)/35
∴ x=1200
Thus, Total number of examines are 1200.
x + y = 30 ... (Equation 1)
x - y = 8 ... (Equation 2)
We can solve these equations by adding them together, which eliminates y:
2x = 38
Dividing both sides by 2 gives us:
x = 19
Now that we have x, we can find y by substituting x into Equation 1:
19 + y = 30
Subtracting 19 from both sides gives us:
y = 11
Now that we have both x and y, we can find their product:
Product = x * y
= 19 * 11
= 209
729 = 27 × 27
√729 = √(27 × 27)
√729 = 27
A hexagon is a polygon with 6 sides.
It has 6 angles, one at each vertex.
It also has 6 vertices.
The perimeter of a rectangle is the total distance around it.
Formula: Perimeter = 2 × (Length + Width).
Total percent increase=Initial populationFinal population−Initial population×100
Increased in 10 years =262,500 − 175,000 =87,500
Increase% = 87,500 / 175,000×100 =50
